GLTeapot perspective 'skewed' over a long period spinning

hrev40238 gcc4hybrid.

If left open and spinning for a period of 6+ hours (just open the app and let it run), something about the perspective changes: it becomes impossible to rotate the teapot to angles past about 30-45 degrees relative to the positive z-axis of the teapot. A bit hard to describe what it looks like, but no matter how much you try to rotate the teapot you cannot see the bottom and cannot get a proper view of the side whereas you can do both these things when the app is first opened.

Closing and reopening GLTeapot fixes the issue, and any new teapots added through the File menu while the first teapot is having this problem appear and rotate fine.
